In this unit we discuss salmon biology and
the life cycle of one of the mightiest and most important species in the
Pacific Northwest, from pre-settlement days and historic Indian harvest
methods to current stock status and recovery efforts. We will
touch on all aspects of the many salmonid species we have in Washington
(and Oregon), focusing on biology, habitat, nutrient recycling, how the
salmon is really a farmer of the ocean, bringing back nutrients from the
rich marine environment and depositing them in the watersheds, threats
to survival, food chain support, and what each individual can do to
help.

Hands-on work may include, depending on
availability, dissection of a hatchery salmon, investigating the air
bladder, anatomy of the gill structure, identification of morphological
features, etc., field trips to local hatcheries can be arranged and
included as part of the curriculum, and students will be left with an
improved view of this majestic fish, its role in the settlement of the
west, and the future.
